About This Tool
The Material Property Comparison tool is a database that lets you compare the physical, mechanical, thermal, and electrical properties of a wide range of engineering materials — metals, alloys, ceramics, and polymers — on a single screen. View key properties such as density, tensile strength, elastic modulus, thermal conductivity, and electrical conductivity side by side to quickly select the best material for your design.
It is especially useful when comparing similar materials within the same category — for example, the difference in corrosion resistance between 304 and 316 stainless steel, or the strength-to-weight (specific strength) comparison among aluminum alloys. Select or search for materials above to compare several at once.

⚠️ Note
The property values in this database are for general reference only. Actual material properties may vary depending on manufacturing process, heat treatment conditions, and alloying element content. For critical designs, always verify against actual test data.
Material Property Comparison Tool pulls materials from a metals/polymers/ceramics database and lines up dozens of properties — density, yield strength, tensile strength, thermal conductivity, electrical conductivity — side by side. Use it to narrow candidate materials in mechanical and structural design, evaluate substitutions, draft specifications, or prepare quotation support data.
Properties sort mechanically → thermally → electrically, shown with Korean names beside the English source items. Alloy compositions (C, Cr, Ni…) appear in their own section, and each material has a visibility switch so you can juggle many candidates at once.

Figures below are widely cited representative values (±a few percent depending on source); loading these three materials shows exactly this picture.
Example 1 — structural steel vs stainless vs aluminium
Compare A36 carbon steel, SUS304, and 6061-T6 aluminium: density ≈ 7,850 / 8,000 / 2,700 kg/m³; yield ≈ 250 / 230–290 / 276 MPa; thermal conductivity ≈ 52 / 16 / 167 W/m·K. Two crossovers stand out. First, stainless matches or beats carbon steel on strength while conducting only one-third the heat — poor for heat exchangers but handy where thermal isolation helps. Second, aluminium reaches similar strength at one-third density, winning strength-to-weight, yet its modulus (~69 GPa vs ~200 GPa) makes deflection and buckling the classic trap.
Example 2 — telling grades apart by composition
Place SUS304 next to SUS316 and the composition section reveals the difference instantly: 316 trades a touch of chromium for 2–3% molybdenum. That single row drives the chloride-resistance gap — seawater, salt spray — and the price gap too. When datasheet numbers look identical, composition is the fastest fingerprint.
* Your query results may differ slightly from these representative figures; the tool follows its source database verbatim.
- Check heat treatment first — the same grade can vary several-fold in yield strength between annealed and T6 conditions.
- Design to the guaranteed minimum of a range, not the average — mid-range assumptions fail on low-end lots.
- Never judge on one row. Marine service cares about fatigue and chloride resistance; high temperature about max service temperature and expansion; electrical parts about conductivity.
- For touching dissimilar metals, mind galvanic potential — the Calomel Potential row hints at this risk.
- Finalize selections with mill certificates and standards documents, and route critical members past a materials engineer — this tool is first-pass screening.
QWhere does this data come from and how reliable is it?
It builds on public materials-engineering databases of the MakeItFrom family, summarizing representative property ranges per material. Because metal properties shift with heat treatment, product form (plate, bar, casting), and test direction, treat these figures as typical values or specification ranges. Final design should be pinned down by mill test certificates or the original national standards (KS D, ASTM, etc.).
QWhy do multiple entries appear under the same material name?
One grade splits into several records by heat treatment (annealed versus quenched-and-tempered), product form, or source specification. Aluminium 6061 plain versus T6 differ in yield strength by several-fold. Match the entry to how your part will actually be procured — that is step one of an honest comparison.
QWhat does a range like '18 ~ 20' mean?
The minimum-to-maximum band the specification allows. For chemistry it is the batch window manufacturers must hit; for properties it reflects within-grade variation. The lower bound usually matters most: yield strength designs to the guaranteed minimum, while for properties where lower is better (thermal conductivity) the upper bound is the pessimistic case.
QWhat is the CSV download good for?
It exports the comparison table for spreadsheet work — building internal standard-material selection documents, conditional-formatting candidate alloys (highlight minimums), or feeding values into calculation sheets. The file mirrors exactly what the table shows, including units and ranges, so double-check those before attaching it to reports.
QWhen should I look at 'Strength to Weight Ratio'?
Whenever mass is a design variable: aerospace and vehicle structures, robot arms, portable-equipment brackets. Against steel, 6061-T6 aluminium loses on absolute strength but can win specific strength thanks to roughly one-third the density. Beware the trap of selecting on specific strength alone — low stiffness (elastic modulus) means larger deflections, so compare modulus and fatigue strength alongside depending on load type.
